A. Initial
B. Repeatable
C. Defined
D. Optimizing

Explanation: It is a characteristic of processes at this level that the focus is on continually improving process performance through both incremental and innovative technological changes/improvements.

A. time
B. bugs
C. failures
D. quality

A. MTTR
B. MTTF
C. MTSF
D. MTBF

Explanation: FIT reports the number of expected failures per one billion hours of operation for a device. This term is used particularly by the semiconductor industry but is also used by component manufacturers.

A. maintainability
B. portability
C. efficiency
D. usability

Explanation: A set of attributes that bear on the relationship between the level of performance of the software and the amount of resources used, under stated conditions.

A. Minimum time to failure
B. Mean time to failure
C. Maximum time to failure
D. None of the mentioned

A. Error seeding
B. NHPP
C. Input domain
D. Halstead’s software metric

A. Telco Systems
B. D-Link
C. Arista Networks
D. ISO 9001

Explanation: Founded in 1988, with over one million products installed worldwide, IMC Networks offers a wide range of fiber media and mode converters for a variety of applications.

A. three
B. four
C. five
D. six

Explanation: The five levels are: initial, repeatable, defined, managed, optimizing

A. forward error recovery mechanism
B. backward error recovery mechanism
C. All of the mentioned
D. None of the mentioned

Explanation: Exception handling is a forward error recovery mechanism, as there is no roll back to a previous state; instead control is passed to the handler so that recovery procedures can be initiated.

A. ISO 9000
B. McCall model
C. Boehm model
D. ISO 9126

Explanation: ISO 9000 is software certification.
